Hanayome: The Sacrificial Bride | Itsuki Kanamura Walkthrough

EDIT: I am not sure if this is a bug or intentional, but it is impossible to obtain Bride ED just by answering all the choices correctly in the game. You would need to collect an additional 20 Affection UP points for each character to obtain Bride ED. The game only provides you 27 times to increase Itsuki’s affection when you actually need 31 chances to make a choice and get the Bride ED.
